A Service Bureau supports multiple Electronic Return Originators (EROs) by providing software, infrastructure, and administrative guidance. Establishing a standardized onboarding system is necessary to maintain IRS compliance and operational efficiency. This guide outlines the technical and regulatory requirements for onboarding new EROs into a Service Bureau model.

1. IRS Framework and EFIN Fundamentals

Every ERO must have a valid Electronic Filing Identification Number (EFIN). In a Service Bureau model, the bureau acts as a provider of software and support, but each sub-office or independent ERO remains responsible for the returns they originate.

EFIN Ownership

Each ERO office must possess its own EFIN. Service Bureaus are prohibited from "renting" or sharing a single EFIN across different business entities. The IRS monitors e-file applications to ensure that the physical location and legal name on the EFIN record match the entity filing the returns.

Suitability Checks

The IRS performs suitability checks on all EFIN applicants. This includes background checks and, in many cases, fingerprinting for principals and responsible officials. Service Bureaus must verify that their clients have successfully passed these checks before provisioning software access.

2. Documentation and KYC Requirements

Onboarding requires the collection and verification of specific documents to fulfill "Know Your Customer" (KYC) standards and IRS due diligence.

Required Documentation List:

  • EFIN Evidence: An IRS EFIN acceptance letter or an e-file application summary dated within the last 12 months.
  • Business Identity: EIN letter, Articles of Incorporation, or LLC Operating Agreements.
  • Government ID: Valid identification for all owners and responsible officials.
  • Banking Information: A voided business check or bank letter for the processing of fees and bank products.
  • Preparer Credentials: A list of PTINs (Preparer Tax Identification Numbers) for all individuals authorized to sign returns within the firm.

3. Georgia-Specific ERO Considerations

For EROs operating in Georgia, compliance extends beyond federal requirements. Georgia tax professionals must adhere to state-specific mandates regarding professional conduct and electronic filing.

Georgia Department of Revenue (DOR) Requirements

EROs in Georgia must be registered with the Georgia Department of Revenue. The state requires that any entity transmitting returns for a fee must maintain a high standard of data security. Georgia-based tax businesses should ensure their written information security plans (WISP) comply with both IRS Publication 4557 and Georgia state privacy laws.

Local Business Licensing

In Georgia, most jurisdictions require a local occupational tax certificate (business license) to operate a tax preparation firm. Service Bureaus should verify that Georgia-based EROs have the necessary local permits to operate legally within their specific county or municipality.

4. Software Configuration and Infrastructure

Once documentation is verified, the Service Bureau must configure the tax software environment for the new ERO.

Configuration Steps:

  1. Office Profile Creation: Enter the legal name, DBA, EIN, and physical address into the bureau console.
  2. EFIN Integration: Link the ERO’s specific EFIN to their profile. This ensures all transmissions are correctly identified by the IRS.
  3. Role-Based Access Control (RBAC): Assign administrative and preparer roles. Admin roles should be limited to business owners to manage fee structures and user settings.
  4. Bank Product Setup: If the ERO offers refund transfers or advances, the bureau must facilitate the integration with the authorized banking partner.
  5. Multi-Factor Authentication (MFA): Enforce MFA for all user logins to protect taxpayer data and satisfy IRS security requirements.

5. Standardized Onboarding Workflow

A structured workflow reduces errors and ensures no compliance steps are missed.

Step 1: Pre-Qualification

Assess the potential ERO’s experience and volume. Review their prior year performance if available. Use the TIG Tax Pros services page to align them with the correct software tier.

Step 2: Agreement Execution

Execute a Service Bureau Agreement that defines the roles, fee structures, and data security obligations of both parties.

Step 3: Verification

Verify the EFIN status through the IRS e-Services portal. Confirm that the business entity is in good standing with the Secretary of State in their respective jurisdiction.

Step 4: System Provisioning

Generate login credentials and provide access to the tax preparation courses or training modules required for software proficiency.

6. Training and Professional Development

Training is a critical component of the onboarding process. EROs must understand the technical aspects of the software and the regulatory requirements of tax preparation.

Essential Training Topics:

  • Software Proficiency: Navigating the interface, entering data, and running diagnostics.
  • Due Diligence: Compliance with EITC, CTC, and HOH requirements to avoid IRS penalties.
  • Security Protocols: Handling sensitive documents and maintaining a secure digital environment.
  • Support Channels: Instructions on how to access technical support through the Service Bureau.

7. Ongoing Support and Quality Monitoring

Onboarding does not end at the first login. Continuous monitoring is required to ensure the ERO maintains high standards.

Monitoring Metrics:

  • Reject Rates: High reject rates indicate a need for additional technical or tax law training.
  • Funding Ratios: Monitor the percentage of returns receiving bank products to ensure proper disclosure and compliance.
  • Security Audits: Periodic checks to ensure the ERO is utilizing MFA and secure document storage.
